A rather beat up example of a Nintendo DSi kiosk unit. These act and function similar to a normal DSi, however once plugged in the unit cannot be turned off.
A random donation from China, the following is a Nintendo DSi SD card used during development of the console.
Sadly, this card is dead and unreadable. These cards would normally contain logs from tests, recovery attempts would also damage this card as you have to open them to recover.
The following is a Nintendo DSi Panda unit used in development for the Nintendo 3DS, the unit would be placed in a Gyroscope unit and connect via a KIS card containing a ribbon cable.
This unit is sadly missing the Gyroscope unit but still has the KIS card, oddly this unit is set into Kiosk mode meaning all text comes up in Japanese with no options to toggle English, this can however be changed by changing a fuse on the motherboard, this fuse was added to prevent factory workers turning the unit off by mistake.
Nintendo Zone was a download service and an extension of the DS Download Station. Users could access content, third-party data, and other services from a hotspot or download station. The service had demos of upcoming and currently available games and may have location-specific content. When the service debuted, users could also connect to the Nintendo Wi-Fi Connection and DSi Shop.
The Nintendo Zone Viewer application allows the Nintendo DSi and 3DS to detect and use the Nintendo Zone service. This application has been discontinued worldwide, but all other Nintendo Zone functionality remains.
